Definitions

  • an object of the present invention is to enable these compounds to be substantially quantitatively decomposed, even at relatively low temperatures and with relatively short residence times.
  • polychlorinated phenyls and/or biphenyls can be substantially quantitatively decomposed at temperatures of as low as about 850° C. and with residence times of as short as 0.1 second in a combustion chamber which operates with extremely intense turbulence and pulsation preferably generated by high-frequency vortex breakoff.
  • Combustion chambers of this kind are known as combustors and, in particular, as pulsocombustors and are described, for example, in "Wasser, Lucas und strigtex” 18 (1974), No. 9, pages 494 to 497.
  • the present invention relates to a process for the thermal decomposition of polychorinated organic compounds such as, for example, polychlorinated phenyls and biphenyls in a flame, which is distinguished by the fact that the polychorinated organic compounds or fuel containing these compounds are heated in a high-turbulence combustion chamber in a pulsating spiral flow at temperatures of at least 850° C. and over residence times of up to 0.1 second, an excess of at least 5% by weight of oxygen, based on the organic carbon to be burnt, being present in the combustion chamber.
  • polychorinated organic compounds such as, for example, polychlorinated phenyls and biphenyls in a flame
  • chlorinated hydrocarbons are added to the combustion air or to the liquid fuel.
  • a chlorinated hydrocarbon content of about 10 -4 to 1% by weight, based on the combustion air, is present in the combustion air.
  • Air extracted from the factory or from the emission sources is used as the combustion air, while oil for example is used as the fuel, waste oil being particularly preferred.
  • the chlorinated hydrocarbons are added to a liquid fuel, they are added in quantities of about 0.1 to 30% by weight, based on the fuel.
  • the cylindrical combustion chamber has the following measurements: diameter 475 mm, length 700 mm, central inlet nozzle for the exhaust air used simultaneously as combustion air: 200 mm diameter.
  • the actual peripheral velocities could not be measured, since, owing to the intensive combustion already present in this cross-section, cooled probes should be used, which were not available.
  • the fuel is fed in centrally via a two component nozzle with ⁇ 30 kg per h of saturated steam of 5 bars.
